1What does the acronym "BIOS" stand for in the context of computer hardware?

A.Basic Input/Output System

B.Binary Integrated Operating Software

C.Boot Initialization and Output Standard

D.Base Input/Output Subsystem

Explanation: BIOS stands for Basic Input/Output System. It is firmware stored on a chip on the motherboard that initializes hardware components during the boot process and provides runtime services for the operating system. Modern systems have largely replaced BIOS with UEFI (Unified Extensible Firmware Interface), which supports larger drives and faster boot times.

2Which component of a CPU is responsible for performing mathematical calculations such as addition and subtraction?

A.Control Unit (CU)

B.Arithmetic Logic Unit (ALU)

C.Cache Memory

D.Memory Management Unit (MMU)

Explanation: The Arithmetic Logic Unit (ALU) is the component of a CPU responsible for performing mathematical operations (addition, subtraction, multiplication, division) and logical operations (AND, OR, NOT). The Control Unit manages instruction sequencing and directs data flow, while cache memory stores frequently accessed data close to the CPU for faster retrieval.

3What is the binary representation of the decimal number 13?

A.1011

B.1101

C.1110

D.1010

Explanation: To convert 13 to binary, divide repeatedly by 2: 13 = 8+4+1, which maps to bit positions 2^3 + 2^2 + 2^0 = 1101 in binary. Binary uses only 0s and 1s, where each digit position represents a power of 2. Understanding binary is fundamental to IT support because computers process all data in binary form.

4Which type of RAM module is commonly used in laptops due to its smaller form factor?

A.DIMM (Dual Inline Memory Module)

B.SO-DIMM (Small Outline DIMM)

C.SIMM (Single Inline Memory Module)

D.RIMM (Rambus Inline Memory Module)

Explanation: SO-DIMM (Small Outline DIMM) modules are the standard RAM format used in laptops, mini-PCs, and other compact devices. They are roughly half the length of standard DIMMs used in desktop computers. Modern laptops typically use DDR4 or DDR5 SO-DIMMs, though some ultrabooks solder RAM directly to the motherboard for space savings.

5What is the primary advantage of an SSD (Solid State Drive) over a traditional HDD (Hard Disk Drive)?

A.SSDs have significantly higher storage capacities per dollar

B.SSDs use spinning magnetic platters for data storage

C.SSDs have no moving mechanical parts, resulting in faster access times and greater durability

D.SSDs generate more heat than HDDs during operation

Explanation: SSDs store data on NAND flash memory chips and have no moving mechanical parts, unlike HDDs which use spinning magnetic platters and read/write heads. This gives SSDs much faster read/write speeds (often 5-10x faster), lower latency, better shock resistance, and quieter operation. The trade-off is that SSDs typically cost more per gigabyte than HDDs.

6A user reports their computer beeps three times on startup and does not display anything on the monitor. What is the most likely cause?

A.The operating system files are corrupted

B.The monitor cable is disconnected

C.A POST (Power-On Self-Test) error indicating a RAM problem

D.The CPU cooling fan has failed

Explanation: POST (Power-On Self-Test) is a diagnostic process run by the BIOS/UEFI when the computer starts. Different beep codes indicate different hardware failures. Three beeps is commonly associated with RAM (memory) errors on many BIOS implementations. Since the error occurs before the OS loads, the issue is hardware-level. The monitor being blank confirms the system cannot complete POST and reach the display initialization stage.

7Which motherboard slot type is most commonly used to connect a modern discrete graphics card?

A.PCIe x16 (PCI Express)

B.AGP (Accelerated Graphics Port)

C.PCI (Peripheral Component Interconnect)

D.ISA (Industry Standard Architecture)

Explanation: PCIe x16 (PCI Express x16) is the standard slot used for modern discrete graphics cards, providing 16 lanes of high-bandwidth data transfer. PCIe has replaced older standards like AGP, PCI, and ISA. The "x16" designation means 16 lanes, providing the highest bandwidth needed for GPU-intensive workloads like gaming and video rendering.

8A technician needs to install an operating system from a USB drive. Which BIOS/UEFI setting must be configured to allow this?

A.Enable Hyper-Threading

B.Disable Secure Boot

C.Change the boot order to prioritize USB devices

D.Enable XMP (Extreme Memory Profile)

Explanation: To boot from a USB drive, the boot order in BIOS/UEFI must be configured so the USB device is checked before the internal hard drive. By default, most systems boot from the internal drive first. Some systems also require Secure Boot to be disabled for non-signed operating systems (like Linux), but the essential step is always setting the USB device first in the boot priority list.

9What does the chipset on a motherboard primarily do?

A.It performs the primary CPU calculations for the system

B.It manages communication between the CPU, RAM, storage devices, and peripheral components

C.It stores the BIOS firmware for system initialization

D.It regulates voltage supplied to the CPU

Explanation: The chipset acts as the communication hub on the motherboard, managing data flow between the CPU, RAM, storage interfaces (SATA, NVMe), USB controllers, PCIe slots, and other peripherals. Modern chipsets are divided into two main components historically called the Northbridge (faster components like RAM and PCIe) and Southbridge (slower peripherals), though many modern CPUs integrate Northbridge functionality directly into the processor die.

10A desktop computer fails to power on at all — no fans spin and no lights illuminate. Which component should the technician check first?

A.RAM modules

B.The power supply unit (PSU) and its connections

C.The CPU thermal paste application

D.The hard drive SATA cable

Explanation: When a computer shows absolutely no signs of life (no fans, no LEDs), the power supply unit (PSU) is the most likely culprit. The technician should verify the PSU is plugged into a working outlet, check that the PSU power switch is on, and test the PSU with a multimeter or PSU tester. A failed PSU provides no power to any component, explaining the complete absence of activity.
